Using Gall Wasps On Oaks To Test Broad Ecological Concepts, P.W. Price, Warren G. Abrahamson Ii, M.D. Hunter, G. Melika Dec 2003

Using Gall Wasps On Oaks To Test Broad Ecological Concepts, P.W. Price, Warren G. Abrahamson Ii, M.D. Hunter, G. Melika

Warren G. Abrahamson, II

Planning conservation of insect herbivores requires knowing what needs to be conserved and developing a set of predictor variables that aid management. We conducted a state-wide survey to examine the species richness of gall wasps ( Hymenoptera: Cynipidae) on six oak species dominant in the threatened scrub-oak vegetation in peninsular Florida. Eighty-eight cynipid species were recorded; 23 were new species to Florida (a 35% increase), including 17 species new to science and 6 species newly recorded in the state. The cynipid species represented 68% of cynipids of Florida, on only 24% of oak species sampled. This fauna represents a hotspot …

Agroforestry, Elephants, And Tigers: Balancing Conservation Theory And Practice In Human-Dominated Landscapes Of Southeast Asia, Philip J. Nyhus, R L. Tilson Dec 2003

Agroforestry, Elephants, And Tigers: Balancing Conservation Theory And Practice In Human-Dominated Landscapes Of Southeast Asia, Philip J. Nyhus, R L. Tilson

Philip J. Nyhus

Large mammal populations theoretically are best conserved in landscapes where large protected areas are surrounded by buffer zones, connected by corridors, and integrated into a greater ecosystem. Multi-use buffer zones, including those containing complex agroforestry systems, are promoted as one strategy to provide both economic benefits to people and conservation benefits to wildlife. We use the island of Sumatra, Indonesia to explore the benefits and limitations of this strategy. We conclude that conservation benefits are accrued by expanding the habitat available for large mammals but more attention needs to be focused on how to reduce and respond to human–wildlife conflict …


Ethics In A Time Of Crises, David A. Bainbridge Dec 2003

Ethics In A Time Of Crises, David A. Bainbridge

David A Bainbridge

Global crises reveal the weakness of our current ethical construct. A more inclusive ethical framework is needed to encourage and support sustainable development and management of resources and restoration of damaged ecosystems.

Discovery Of The First Male Specimen Of Tantilla Hendersoni Stafford, Josiah H. Townsend Dec 2003

Discovery Of The First Male Specimen Of Tantilla Hendersoni Stafford, Josiah H. Townsend

Josiah Townsend

Tantilla hendersoni Stafford, 2004 was described based on a single female specimen from Cayo District, Belize, and is the only snake species considered to be endemic to the country. We report the discovery of a second specimen, the first male, of Tantilla hendersoni from a new locality in Stann Creek District, and provide a detailed morphological description of the specimen. We also discuss the distribution, conservation, and taxonomic status of the species.


Peace & Well Being For All, Emmanuel Ohene Afoakwa Dec 2003

Peace & Well Being For All, Emmanuel Ohene Afoakwa

Professor Emmanuel Ohene Afoakwa

Peace is not only the absence of armed conflict, it is also a dynamic set of relationships of coexistence and co-operation among and within peoples, characterized by respect for human values and concern to provide the greatest possible well-being for all. Peace is increasingly threatened each day by the accumulation of weapons of mass destruction, by the great economic and social inequalities that divide mankind, and by contempt for basic human rights and the dignity of the individual, requiring a greater effort to overcome these evils. This is only possible in a world in which the observance of international law …


Recruitment Of The Puf3 Protein To Its Mrna Target For Regulation Of Mrna Decay In Yeast, Wendy Olivas, J. S. Jackson, S. S. Houshmandi, Leban F. Lopez Dec 2003

Recruitment Of The Puf3 Protein To Its Mrna Target For Regulation Of Mrna Decay In Yeast, Wendy Olivas, J. S. Jackson, S. S. Houshmandi, Leban F. Lopez

Wendy Olivas

The Puf family of RNA-binding proteins regulates mRNA translation and decay via interactions with 3' untranslated regions (3' UTRs) of target mRNAs. In yeast, Puf3p binds the 3' UTR of COX17 mRNA and promotes rapid deadenylation and decay. We have investigated the sequences required for Puf3p recruitment to this 3' UTR and have identified two separate binding sites. These sites are specific for Puf3p, as they cannot bind another Puf protein, Puf5p. Both sites use a conserved UGUANAUA sequence, whereas one site contains additional sequences that enhance binding affinity. In vivo, presence of either site partially stimulates COX17 mRNA decay, …

Innovation Education In Nsw Design And Technology Curriculum, A Turner, K Seemann Dec 2003

Innovation Education In Nsw Design And Technology Curriculum, A Turner, K Seemann

Dr Angela Turner

Do technology teachers in secondary schools and academic stakeholders share the national vision of knowledge and innovation when implementing Design and Technology curricula? Directions for an innovation climate have been endorsed by the federal government, and demanded by various industry groups, since 1996. This paper explores the extent to which education providers of secondary schooling have embraced the call for teaching and developing innovation capacities through technology curriculum. The Australian Science, Technology and Engineering Council (ASTEC) in 1996 underpinned “foresight” as an essential dimension to our thinking which attempts to capture the dynamics of change and the need to incorporate …

Performance Modeling And Analysis Of Blood Flow In Elastic Arteries, Dr. Anil Kumar Dec 2003

Performance Modeling And Analysis Of Blood Flow In Elastic Arteries, Dr. Anil Kumar

Dr. Anil Kumar

The effect of magnetic field has been examined on rheological models of blood. ONE., of them is the Power Law model and the other is the generalized Maxwell model. It is noticed that the magnetic field has a significant effect on the flow phenomena. The investigation shows that the model considered here is capable of taking into account the theological properties affecting the blood flow and hemodynamic features, which may be important for medical doctors to predict diseases for individuals on the basis of the pattern of flow for an elastic artery in the presence of a transverse magnetic field. …
